Yūka Nishio

, better known by her stage name is a Japanese musician, singer, voice actress and DJ from Kanagawa Prefecture who is affiliated with Hibiki. She was formerly active as a solo musician under the name Haruca, releasing the single "Eien no Kotae" in 2017. She is known for her roles as Nanami Hiromachi in BanG Dream!, where she also serves as the bassist of the band Morfonica, and as Rinku Aimoto, the protagonist of the multimedia franchise D4DJ.

Biography Nishio was born in Kanagawa Prefecture on March 31, 1994. During her youth, she played the violin and was in an orchestra in elementary school before quitting as a middle schooler.

She also had an interest in anime and manga from an early age, and upon entering Keio University, she decided to pursue a career as a voice actress.

In April 2019, she joined the talent agency Hibiki following an audition, and changed her stage name to Yūka Nishio. Later in the year, she was cast as Rinku Aimoto, the main protagonist of the franchise D4DJ and member of the unit Happy Around!. Before joining the series, Nishio had DJing experience at a club. She also voiced Yuu Higashiyama for the collectible card game Rebirth for you and its corresponding anime Rebirth.

In 2020, Nishio joined the music project BanG Dream!, voicing the character Nanami Hiromachi as well as becoming bassist of the band Morfonica. She was unfamiliar with the bass guitar prior to joining the band; as Morfonica is a rock violin group, Nishio developed a rapport with violinist and bandmate Ayasa over their mutual background in the instrument. Nishio co-hosts the YouTube series Monica Radio alongside bandmate Hina Suguta. On August 22–23, she participated in the BanG Dream! 8th Live by performing with Happy Around! as the opening act to Raise A Suilen's The Depths concert and with Morfonica on the following day's Special Live: Summerly Tone.

On April 21, 2022, Hibiki announced Nishio had tested positive for COVID-19, forcing her to skip upcoming events like Morfonica's Resonance concert and D4DJ anniversary program. For the former, backing tracks of her vocals and bass were used in her place.
